Personal History
Pavel Chekov, son of Andrei Chekov, was born in Russia on Earth in 2245. Pavel was an only child, however he once believed, while under the influence of the Beta XII-A entity, that he had a brother named Piotr who was killed by the Klingons. Around 2263, Chekov entered Starfleet Academy, from which he graduated with the rank of ensign. His Starfleet serial number was 656-5827D.

During the early-2260s, Pavel was romantically involved with Irina Galliulin, while they both attended the Academy together. The two had several disagreements before they parted ways: Pavel believed Irina to always be too free-spirited, Irina believed Pavel to have always been rigid. When Irina dropped out of the Academy, each accused the one of leaving the other. Pavel left, but came back to look for Irina, who was at the time staying in the city with friends. Irina would eventually join the counterculture movement of Dr. Sevrin, and his search for the mythical planet Eden.

Chekov's first assignment, at the age of 22, was on the USS Enterprise under command of Captain James T. Kirk. He joined the crew in 2267 after his graduation from the Academy. Chekov served a standard junior officer rotation, eventually earning the post of navigator, although he was also proficient with the science officer station, often serving at the post in Spock's absence. While acting the role of science adviser, Chekov made every attempt to be as thorough as possible. While investigating a humanoid that could generate and control energy, who referred to himself as Apollo, in 2267, Chekov began to spout off information on similar creatures. After naming the electric eel and giant dry-worm, he was stopped by Doctor McCoy, who told him "not the whole encyclopedia, Chekov," later quipping on Chekov's dedicated thoroughness by stating: "Spock's contaminating this boy, Jim." On a mission to deliver supplies to a Federation experimental colony on the planet Gamma Hydra IV, the six member landing party discovered that most of the colonist were either dead or close to death from rapid aging with Chekov becoming frightened upon finding the dead body of Alvin in one of the buildings. On return to the Enterprise, the entire landing party was infected with the rapid aging except for Chekov. Chekov complained to Sulu about how many times Doctor McCoy put him through a series of tests to discover why he wasn't aging, especially emphasizing that if he gave any more blood he wouldn't have any left. Spock soon discovered that the rapid aging was caused by radiation left on Gamma Hydra IV from a rogue comet. McCoy determined that the cure was adrenaline. Chekov had been so shocked upon finding the dead body that his adrenaline provided an immunity to the radiation's effects. When the ship was hijacked by android Norman to an undiscovered planet, the Enterprise's crew discovered Harcourt Fenton Mudd who had crashed on the planet. The planet was populated by androids who wished to use the Enterprise to visit other planets, but strand the crew there. The androids tempted Chekov with a planet full of beautiful women to serve him. In the end, the crew banded together and escaped the planet, leaving Mudd with five hundred android replicas of his overbearing wife, Stella. During shore leave on Deep Space K-7, Chekov, along with Uhura, brought one tribble to the Enterprise, which reproduced so fast that the ship became overrun with them in three days. Chekov, Kirk, and Uhura were captured by alien beings who used them in gladiatorial combat, which the beings wagered on. Such captured beings were known as "thralls." One of the thralls, Tamoon, who was assigned to train Chekov in gladiatorial combat, developed romantic feelings toward him, leading to many unwelcome advances. In 2268, Chekov, Kirk, and Lieutenant Uhura were captured by alien beings who used them in gladiatorial combat, which the beings wagered on. Such captured beings were known as "thralls". One of the thralls, Tamoon was assigned to train Chekov in gladiatorial combat and developed romantic feelings towards him, leading to many unwelcome advances. Chekov was at navigation when he noticed the Enterprise navigation controls were not working, and then tried to assist Lieutenant Hadley, manning the helm, with the helm's stuck controls. The Kelvan Hanar then suddenly transported himself onto the bridge and put Chekov and the rest of the bridge crew into temporary motionless stasis. Two other Kelvans, Tomar and Drea, had already seized control of engineering and environmental engineering in a similar fashion. Thus began the attempted hijacking of the Enterprise by the Kelvan Milky Way Expedition so they could return to the Andromeda Galaxy. After the Enterprise successfully exited the Milky Way galaxy through the galactic barrier, Kelvan leader Rojan neutralized and reduced Chekov into a dehydrated porous cuboctahedron solid the size of a Human fist, composed of Chekov's base minerals which represented the "distilled" essence of Chekov's being, because he was considered along with most of the rest of the crew non-essential personnel. Chekov was reconstituted after Kirk, Spock, McCoy, and Scott, the only four of the crew who were not neutralized, regained control of the Enterprise.

In 2268, Chekov was killed during a mission to make contact with the Melkotians. The Melkotians consider the humans as a disease that must be destroyed, and place them in a frontier setting during the time of Wyatt Earp. The away team fills the role of the Clantons, one of the two major groups involved at the OK Corral gunfight. Chekov is killed by one of the Earps over a girl named Sylvia, who was in love with him, and not the Earp that wanted her. Spock realized that this simulation was not real, and thus the away team could not be hurt as long as they did not believe in the illusion. After successfully escaping the illusory Wild West setting, the crew was transported back to the Enterprise, along with Chekov who was alive once again. After the Starnes Exploration Party children were brought aboard the Enterprise from the planet Triacus, no one on board knew that the children were under the influence of Gorgan, who had given the children the ability of mind-control. This telekinesis had already caused the deaths of the children's parents and was the way in which Gorgan hoped to achieve galactic dominance by way of other children. The children used their mind-control on Chekov, Sulu, and Uhura to make them believe that the Enterprise was still orbiting Triacus, when in actuality Chekov and Sulu had set course for Marcus XII, the intended next target for Gorgan. This also caused Kirk, unaware of the change of course and the departure from the orbit of Triacus, to have two crewmen have their molecules beamed into and spread throughout space and to their deaths. Then Tommy Starnes manipulated, by telekinesis, Chekov, Security Chief Freeman, and another security guard to attempt to arrest and put in the brig both Kirk and Spock because of false "orders" of Starfleet command. Kirk and Spock fought off Chekov, Freeman, and the other security guard, who were temporarily put in the brig themselves. Chekov was freed from the mind-control once the children were freed from the influence of Gorgan. Chekov was rendered unconscious by the Eymorg Kara when she boarded the Enterprise and used her control bracelet in order to steal Spock's brain. After the crew regained consciousness and found Spock's body without his brain and they found Kara's ship left an ion trail to the Sigma Draconis system, Chekov placed a schematic of the system on the bridge's viewscreen. A debate ensued between Chekov, Sulu, and Uhura as to which of the three class M planets they should look for Spock's brain, with Kirk reminding them that Doctor McCoy said that Spock would have only three hours to live without his brain. None of the three planets seemed capable of supporting interstellar flight, but Kirk's best hunch of where to look came from Uhura, who found large, regular energy pulsations on the otherwise glaciated and pre-industrial Sigma Draconis VI. Chekov was part of a landing party that also consisted of Kirk, Scott, McCoy, and two crewmen who beamed down to the surface of Sigma Draconis VI. There the landing party suffered an ambush by the Morg, primitive humanoid men, until one of them was subdued by a phaser. The Morg that was hit hinted at "the Others" who gave "pain and delight", but seemingly the Morg had no mates and didn't know what a female was. Chekov then ran his tricorder and found evidence of an underground city. Kirk, McCoy, and Scott went underground and found that the Eymorg were the females of the Morg and discovered Spock's brain was being used to power the city, Chekov used his phaser to heat a rock to keep him and the two crewmen warm. McCoy was able to get Spock's brain back in his head, just in the nick of time, and they met back up with Chekov and the two crewmen leaving the Eymorg to have to start living with the Morg. When Spock mind-melded with Medusan Ambassador Kollos to guide the Enterprise into normal space after being stranded in an uncharted void of the galaxy by a then-dead Larry Marvick, Spock-Kollos took over, temporarily, the helm console from Sulu and was assisted in the task by Chekov at navigation. Unfortunately Spock-Kollos forgot to put back on the visor, which caused Spock to go temporarily insane while still on the bridge. During this temporary insanity, he pushed very hard backwards both Chekov and Sulu, who were trying to help him, with Chekov landing on top of the navigation console and then to on his back on the floor. Fortunately Chekov recovered quickly and Spock did so, as well, a short time after that. Chekov was part of an away team that beamed aboard the starship USS Defiant, which was adrift in space. They discovered that the ship was dissolving due to the effects of the interphase of that part of space. They also discovered that there had been mass insanity aboard the USS Defiant with its whole crew dead. Kirk unfortunately had to remain behind because the transporter could only beam aboard three of the four away team members. After beaming back to the Enterprise, Chekov attacked Spock on the bridge in a fit of madness. The illness then spread throughout the ship. The interphase was causing mental breakdowns in the crew of the Enterprise. Chekov was cured of his madness the same way the rest of the crew who suffered mental breakdowns did, from Dr. McCoy discovering and then dispensing a diluted theragen derivative. Spock told Chekov that it was great to see Chekov back to his normal self. The crew rescued Kirk and escaped the Tholians. Near the end of 2268, Chekov was very nervous when Kirk, Spock, and Scott were forced to activate the three-part self-destruct sequence in order to force Commissioner Bele to relinquish control of the Enterprise to Kirk. Shortly after in the recreation room, Chekov attended the speech by Lokai regarding how his people had been enslaved and then subjugated by Bele's people on their home planet of Cheron for many centuries. Chekov expressed surprise about this by saying to Lokai, "There was persecution on Earth once. I remember reading about it in history class." Sulu then reminded Chekov that that took place several centuries earlier on Earth and was considered primitive thinking in the 23rd century. Chekov, manning the bridge's main science station for Spock, was later the one to discover that Bele sabotaged the self-destruct program so he and Lokai ended up having their final battle on the already mutually annihilated, by civil war, Cheron. Early in 2269, Chekov's sight was affected when the "lights of Zetar" beings attacked the Enterprise as the ship was trying to reach Memory Alpha. Apparently as navigator, Chekov's sight was considered by the Zetarians to be the most important part of Chekov's brain to render useless in the young man during the attack. Chekov later expressed that he couldn't force himself to look at the navigation controls during the attack. Later in 2269, Chekov would once again encounter his lost love, Irina. Initially happy to see one another, Chekov adamantly disapproved of her new lifestyle and attempted to cast her off. She visited Chekov, who was working in Auxiliary Control assigned to help Spock locate Eden, to apologize for upsetting Pavel. Her ulterior motive, however, was to subtly use him to gain his knowledge of the systems of the ship, which were later used by Sevrin for hijacking the Enterprise. The two would leave each other once again, this time while saying "good-bye" to one another, as well as each with a better understanding of the other. A short time after that unaware that Kirk's body was being inhabited by Doctor Janice Lester after a life-energy transfer, Chekov and Sulu started protesting when the captain extended the mutiny charges against Spock and the doctor to Scott and McCoy and ordered the death penalty for all four of them. Chekov persisted and tried to remind the captain that the death penalty was forbidden except for violation of General Order 4, which had not been violated. But the captain refused to listen. A short time later on the bridge, Chekov and Sulu took their hands off their consoles in defiance of the captain's orders to go to the planet Benecia for the internment of the prisoners. This action by Chekov and Sulu fortunately started the process of returning Kirk back to his own body.

By the early 2270s, Chekov had been promoted to lieutenant and served as the security chief and tactical officer of the refit Enterprise under the command of Captain Willard Decker. Chekov was manning the weapons console when the Enterprise entered a wormhole created by its imbalanced warp engines. Kirk ordered Chekov fire phasers on an asteroid they were going to collide with in the wormhole, but Decker ordered that he fire photon torpedooes at it instead. Slowly, Chekov fired the weapons due to the wormhole effect but ultimately saved the ship. Later, Chekov's hands were severely burned when the ship was probed during its encounter with V'ger.

Chekov was later promoted to commander and assigned as first officer to USS Reliant under Captain Clark Terrell. In 2285, Reliant was on a mission to find a suitable planet to conduct trials with the Genesis Device. When they explored Ceti Alpha V, Chekov and Captain Terrell encountered Khan Noonien Singh and his augments. By putting Ceti eels inside their heads, Khan made them susceptible to his suggestions, his motive being to seek revenge on Admiral Kirk. Using Chekov and Terrell, Khan was able to seize the Reliant and subsequently steal the Genesis Device. After Captain Terrell's death, and the departure of the Ceti eel from his head, Chekov recovered in time to help defeat Khan in the battle of the Mutara Nebula. Afterward he assumed the post of Enterprise's acting science officer following the death of Captain Spock. Also in 2285, Chekov and his shipmates Kirk, Scotty, Sulu, and McCoy stole the Enterprise from Spacedock (with Uhura's help) in an attempt to recover a regenerated Spock from the Genesis Planet. The Enterprise was disabled by a Klingon Bird-of-Prey in orbit around the Genesis Planet, and was then self-destructed by Kirk (with help from Scotty and Chekov) to prevent its capture. Kirk and his crew later seized command of the Klingon ship, which they named the HMS Bounty. The crew then transported the regenerated body of Spock to Vulcan, where the body would be reunited with his katra, which had been placed in McCoy. Using the slingshot effect, the Bounty went back in time to 1986, to transport two Humpback whales to the 23rd century. While on Earth, Chekov and Uhura were part of "Team 2," assigned to locating and acquiring photons for recrystallizing the dilithium crystals aboard the Bounty. Although the mission was a success in acquiring the necessary photons from the nuclear vessel, USS Enterprise, Chekov was captured by the ship's security. Accused of being a "Russkie," Chekov made a failed escape attempt from the aircraft carrier, only to become critically injured when he fell over fifty feet from the ship's hangar deck, running through an open hatch that led out to one of the ship's massive aircraft elevators. Chekov was taken into emergency surgery at Mercy Hospital where he was diagnosed with a tearing of the middle meningeal artery after a fundoscopic examination. He would successfully be healed, narrowly escaping the removal of an Epidural hematoma by trepanation, and subsequently evacuated from the hospital by McCoy, Kirk and Gillian Taylor. Upon returning to the 23rd century, Chekov and his shipmates faced court martial for their actions. However, they were eventually cleared of all charges, and Chekov was reassigned as second officer, Navigator, and security chief on the USS Enterprise-A.

In 2287, Chekov took command of the Enterprise-A and posed as "Captain Chekov" as a ruse to negotiate with Sybok for the hostages that the renegade Vulcan took on Nimbus III, while Kirk, Spock, Uhura, and a security team landed on the planet covertly by shuttlecraft. Chekov successfully distracted Sybok long enough for the landing party to launch an attack on Paradise City. Sybok later captured the landing party and boarded the Enterprise. Making his way to the bridge, Sybok confronted Chekov and took away his "pain". Afterward, Chekov became one of the Vulcan's followers. In early 2293, Chekov undertook his final voyage on the Enterprise-A as part of the mission to escort the Klingon Chancellor to peace negotiations with the Federation. Chekov used his investigative science background to find forensic evidence linked to a Federation-Klingon conspiracy attempting to undermine the peace talks. After the Khitomer Conference, Chekov's last duty on the Enterprise-A was to man navigation and the helm for her decommissioning cruise. In the latter part of 2293, Commander Chekov was a guest of honor aboard the new USS Enterprise-B under the command of John Harriman. During the maiden voyage, Captain Kirk went missing (presumably swept into space) during a hull breach caused by a part of the Nexus energy ribbon when it collided with the Enterprise-B.

After the decommissioning of the Enterprise-A and his role in the launching of the Enterprise-B Pavel accepted Sulu's offer to serve on the Excelsior as First Officer. After serving for many years as first officer aboard the Excelsior, he was promoted to captain and assumed command of the USS Undaunted. On one of his assignments on the Undaunted, Chekov made first contact with an enigmatic race known as the Watraii, who hid their true visages behind masks. The contact was brief as the Watraii had little or no interest in contact with other species.

For eight years he commanded the Potempkin before he was promoted to Commodore and assigned a desk on Earth. His promotion to Rear Admiral in 2327 had him take over the academy a position he held until he became the DCinC in 2349 a position he held for fifteen years. In 2364 Pavel was promoted to Fleet Admiral and became the CinC of Starfleet.
